Machine-readable details of errors

[Jeroen-VdB]

Would it be interesting to add an RFC 9457 Problem Details for HTTP APIs inspired extension for error handling?

An example could be:

{
    "specversion" : "1.0",
    "type" : "com.example.someproblem",
    "source" : "/mycontext",
    "subject": null,
    "id" : "C234-1234-1234",
    "time" : "2018-04-05T17:31:00Z",
    "datacontenttype" : "application/problem+json", // specific media type
    "status" : "error",
    "title": "Processing failed",
    "detail": "An error occurred while processing.",
    "data" : {
         ...
    }
}

I'm currently looking into implementing error handling in asynchronous processes. I'm always in favour of using as much standardization as possible. Up until now, I was not able to find anything specific about asynchronous error handling.
Unless these details should remain domain-specific, and therefore reside only in data.

Ps: As mentioned in the RFC: Problem details are not a debugging tool for the underlying implementation;. Therefore I see a distinction between this and the already existing Severity Extension.
